Curiosity is growing as fans wonder how many seasons Slow Horses could have. The gripping spy thriller has become hugely popular among the masses. Based on Mick Herron’s Slough House novels and starring Gary Oldman and Jack Lowden, Season 4 has just premiered. While fans await release details for Slow Horses Season 5, the creators have also announced the renewal of Season 6. Many are wondering how many seasons the Apple TV+ series could have.

Here's everything we know about how many seasons Slow Horses could have and what showrunner Will Smith has to say about it.

Slow Horses could continue for many more seasons if the current trend continues. Showrunner Will Smith has expressed his desire to adapt all of Mick Herron’s novels, but the final decision rests with Apple TV+.

Speaking of future seasons, producer Will Smith has confirmed that he plans to bring all of the books to the screen. "I think Mick is writing the ninth one right now, but we'll have to see what happens. It depends on what Apple wants and what the appetite is, but I definitely have a 'leave them wanting more' instinct rather than an 'outstay your welcome' instinct … But the world of the show is there to be explored," Smith said.
